ARM Data Archive Registered with Elsevier
Apr 02, 2014       
With an ever-increasing need to connect related pieces of information, databases rule the world. As of mid-March, the ARM Data Archive—containing two decades of continuous measurements of clouds, aerosol, precipitation, and radiative energy from ARM sites around the world—is now included on the data repository page of the highly-regarded scientific publisher, Elsevier. Listed under [...]

Ensemble Large-Scale Forcing Data for the MC3E Campaign Available
Feb 26, 2014       
Ensemble forcing data from the Midlatitude Continental Convective Clouds Experiment (MC3E) were developed by considering uncertainties in precipitation observations using the analysis described in Zhang and Lin [1997] and Zhang et al. [2001]. MC3E was a major ARM field campaign conducted from April to June 2011 near the ARM Southern Great Plains (SGP) site to [...]

Derived Wind Profile Data from Doppler Lidar Ready for Review
Feb 26, 2014       
Vertically-resolved wind measurements are crucial for numerical weather prediction and for modeling pollutant and aerosol transport. The scanning, coherent Doppler lidars operated by the ARM Facility have the capability of providing accurate, high-resolution wind measurements within the atmospheric boundary layer. A new Doppler lidar wind profile value-added product (VAP) is available as an evaluation product. [...]

New ARM Best Estimate Land Product Contains Critical Soil Quantities for Describing Land Properties
Sep 19, 2013       
The ARM Best Estimate: Land (ARMBELAND) value-added prduct (VAP) is a subset of the ARM Best Estimate (ARMBE) products designed to support community land-atmospheric research and land model developments. It contains several critical soil quantities that ARM has been measuring for many years for describing land properties. The quantities in ARMBELAND are averaged over a [...]

Value-Added Product Estimates Planetary Boundary Layer Height from Radiosondes
Sep 12, 2013       
The planetary boundary layer (PBL) height (or mixing layer depth) can vary significantly with time due to a number of factors including large-scale dynamics, cloudiness, convective mixing, and the diurnal cycle of solar radiation. The structure and depth of the PBL is important to a wide range of atmospheric processes including cloud formation; aerosol mixing, [...]

New Data Available for Precipitation Value-Added Product
Aug 29, 2013       
The Quantitative Precipitation Experiment (QPE) value-added product (VAP) contains precipitation rates gathered by the C-band scanning ARM precipitation radar (C-SAPR). Data are now available for September 2011, covering the ARM Madden-Julian Oscillation (MJO) Investigation Experiment (AMIE). Due to some issues with the radar system a polarimetric-based estimate was not possible. Instead, a [...]

Large-Scale Forcing Data for AMIE-Gan Available for Evaluation
Aug 19, 2013       
The large-scale forcing data for the ARM MJO Investigation Experiment (AMIE) on Gan Island in the Maldives are now available for use and evaluation by the cloud modeling community. AMIE-Gan was conducted during the period October 2011 to March 2012 in conjunction with the Dynamics of the Madden-Julian Oscillation (DYNAMO) and Cooperative Indian Ocean experiment [...]

Evaluation Value-Added Product Estimates Organic Aerosol Components
Jul 23, 2013       
Organic aerosol (OA, i.e., the organic fraction of particles) accounts for 10–90% of the fine aerosol mass globally and is a key determinant of aerosol radiative forcing. But atmospheric OA is poorly characterized and its life cycle insufficiently represented in models. As a result, current models are unable to simulate OA concentrations and [...]
